Abstract
The utility model relates to an outer-tooth internal spiral heat exchange tube, which comprises a tube body (1). The outer-tooth internal spiral heat exchange tube is characterized in that teeth (2) are rolled on the circumferential surface of the outer wall of the tube body (1); spiral fins (4) are rolled on the inner wall of the tube body (1); the teeth (2) are strip-shaped; the direction of the teeth (2) is parallel to the axial line of the tube body (1); the cross sections of the teeth (2) are trapezoidal; and a V-shaped groove (3) is formed between two adjacent teeth (2). The outer-tooth internal spiral heat exchange tube has favorable heat transfer performance; the strip-shaped teeth are arranged on the outer wall of the tube body, so as to play the role of guiding; the spiral fins are arranged on the inner wall of the tube body, so as to increase the heat exchange area and enhance the heat exchange effect; and the outer-tooth internal spiral heat exchange tube is suitable for the production process of crude oil refining.
Description
(1) technical field
The utility model relates to a kind of heat exchanger tube, is specifically related to a kind of external tooth internally spiral heat-exchanging tube.
(2) background technology
Pipe heat exchanger is widely used in petrochemical industry because of it has excellent heat transfer and withstand voltage properties.But most light pipe or screwed pipes of using in the pipe heat exchanger in the crude refining production process, it does not have dredges and discharging effect smoothly, causes the heat transfer property of heat exchanger low, makes its generation cavitation phenomenons and makes device damage.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and have the effect of dredging, heat exchange efficiency height, is suitable for the external tooth internally spiral heat-exchanging tube that uses in the crude refining production process.
The purpose of this utility model is achieved in that a kind of external tooth internally spiral heat-exchanging tube, it comprises body, it is characterized in that: rolling teeth on the described tube wall side face, the rolling helical fin of described inboard wall of tube body, described teeth are elongated, its direction is parallel with the body axis, and described teeth cross section is trapezoidal, forms " V " font groove between the adjacent teeth.
Compared with prior art, the beneficial effects of the utility model are:
A kind of external tooth internally spiral heat-exchanging tube of the utility model, good heat-transfer, the setting of tube wall strip teeth has the effect of dredging, and the setting of inboard wall of tube body helical fin increases heat exchange area, and the enhanced heat exchange effect is suitable for using in the crude refining production process.
(4) description of drawings
Fig. 1 is the sectional schematic diagram of the utility model external tooth internally spiral heat-exchanging tube.
Wherein:
Body 1, teeth 2, groove 3, helical fin 4.
(5) specific embodiment
Referring to Fig. 1, a kind of external tooth internally spiral heat-exchanging tube that the utility model relates to, it comprises body 1, rolling teeth 2 on the described body 1 outer wall side face, described body 1 is rolling helical fin 4;
Described teeth 2 are elongated, and its direction is parallel with body 1 axis.
Described teeth 2 cross sections are trapezoidal, form " V " font groove 3 between the adjacent teeth 2.
Claims (1)
1. external tooth internally spiral heat-exchanging tube, it comprises body (1), it is characterized in that: rolling teeth (2) on described body (1) the outer wall side face, the rolling helical fin of described body (1) inwall (4); Described teeth (2) are elongated, and its direction is parallel with body (1) axis, and described teeth (2) cross section is trapezoidal, form " V " font groove (3) between the adjacent teeth (2).
